Patented May 27, 1952 UNITED STATES PATENT 0F1F l CE 2,598,067 KITCHEN .CABINET INGINERATOR Yincent It. QBrien, St. Pa1.11 Application September 3, 1946, Serial N 0. 694 473 1 invention relates to a cabinet incinerator primarily ada ted to be ocated in the kitchen f a dw llin ands-slicin :i rmed as'part-of'the kitchen ca inet so as to rov de. in a Ye -lent place a tedi pc a ccm tment in he o n in nerator so t at wa te-such assarhase, paper and hernia-m t l c-crs ass aiae alea be distr ssed byzconsi mins the same with fire toreduce it 13. ashes.

A feature resides in providing within the hitch! n a et adja ent-to and formin art f h kitchen sinkcabinet andthe heatinsulatedcom partment in which a he t n elemen su h a a as bu n oran electrichea ine elem nt may b o ided o as o orm such heat within th cable t to reduce e was e. garbage or other material to ashes to be disposed of such refuse which accumulated in a household and is ordinarily rt cu arly in the kitchen.

is s a eature to p ovi e a disposal un j c the s nk which is the term of an incinerator and which is formed with a 119mm!- able waste basket memb r whi h be lifted out of the cabinet as desired and thus can be replaced-as necessary if desired.

My kitchen cabinet incinerator includes a receptor-for the waste material which is connected with thesewer disposal system and wherein the receptor is connected with the water system of the building in which the incinerator is located so that when the garbage or waste material has been reduced to ashes and the incinerator flame is extinguished a valve willoperate to flush water into the .bottomrof the receptor and in turn wash the ashes from thereceptordown into the sewage disposal system. Thus I provide a kitchen cabinet incineratonas having a unique means of completely disposing garbage, refuse and other material to be incinerated and after it has been educed to ashes it is washed down'into the ewage system of the building; thereby completely cleansing the receptor making it ready to receive snore material which is "to be disposed of.

a further object of my invention resides in mending a blower located :in the compartment in th agabinet next to the :Wasteincinerator compart ient for blowing air under the gas rin or heating element and through the incinerator to an outside flue tocarry away any fumes or gases given off rirorn the incinerator in its operation.

A teatupe of *primary importance resides in proyiding incinerator compartment built in- 9 1G .liitchehsink cabinet and which compartmeat ls'completclyinsuiated on. all sides includ- 7 ear (01. 110-18) control lock for the incinerator door which willwhile the incinerator is burning:

lock the door the waste material, thus keeping the fumes, smoke or soot from -the incinerator within the incinerator cabinet until the ashes have been washed into the sewer by means of the water-conwhich receives the ashes.

The grate in the basket of my incinerator'may be cleansed of ashes by gently rocking the incinerator door open and shut. Thus my in cinerator cabinet'requires no shaking grates or ash receiving drawers which have to beoperated and cleansed. This simplifies the construction of my incinerator and by means of the flushing operation, my ash receiving bowl in the bottom of the incinerator will be thoroughly cleansed. The water flushing means may be operated to dampen the ashes in the incinerator before the door is shaken; thus eliminating any-dust from the ashes coming out into the room.

My incinerator cabinet is conveniently located to the sink andworkboard of the kitchen cabinet wherein the incinerator located and the incinerator may be made with various types c-f doors. One type of door -for incinerator resides in the swinging form wherein the top of the door swings outwardly into the roomand the bottom of the door is hinged. The garbage and waste disposal basket is ren oyably attached to the door and swings with itinto open "position.

Another type of my incinerator door resides in a swinging formwhere the deor is hinged onto its vertical side and the other side. is 'free to sw g u to the ro m Th ty e cfdoor a so carries a triangular shaped bashetiior receiving the material to .be disposed.

Still another type oi door for my kitchen cabinet n i r're des n a p ty e drawer with a door. A heavyinsulated door front forrnsthe front wall of the drawer.

My inc n r o c bine may he termed with an o a i s ng b om which' is a a ted to close the bottom of the receptacle-pf the cinerator when the door is open to prevent ashes nection from the sink to the incinerator bowl from dropping on to the kitchen floor when the incinerator is opened. This bottom closure is particularly adapted to the drawer type of incinerator and also to the cabinet where the door is hinged on to the side.

In the drawings forming part of my specification:

Figure 9 is a similar section of Figure 8 showing a form of the door for the front of the incinerator cabinet which is hinged on one of its vertical edges to allow the door to swing outwardly into the room.

Figure 10 is a partial front view of the incinerator showing an arrangement for the controls thereof.

My kitchen cabinet incinerator A includes an incinerator compartment built into one side of the kitchen cabinet as illustrated in Figure l. The incinerator compartment B includes a compartment having an incinerator chamber (B which is surrounded with heavy heat insulation H so that the heat in the incinerator will not escape to the outer walls of the: cabinet A. The cabinet A includes a sink C having water connections from any suitable source of supply to the faucet of the sink.

The incinerator compartment B is formed with a tiltable door l2. The door is also heavily insulated by the insulating material I I. The door I2 is adapted to swing outward from the cabinet A to expose the open top I3 of the refuse receiving basket l4 which is mounted on the swinging door H in a manner so it may be removed when desired. The bottom l5 of the basket is in the form of a grate so that ashes accumulated in the basket may fall down into the bottom of the bowl It.

The bowl it of the incinerator B is connected by a large outlet II to the sewer system of the building in which the incinerator cabinet A is located. In the bowl I6 I provide a gas or electric burner l8 which may be regulated in any suitable manner and may be controlled by timeclock or mechanism l9 illustrated in Figure 1 and located on the front of the cabinet A. I have not illustrated the detail of the timeclock or control mechanism (9, which may be of any suitable construction.

In the base of the bowl I6, I provide a water flushing unit or ring 20 which is connected by the pipe 2| to the water supply 22 and which is controlled by the valve 23. The pipe 22 leads to the water faucet 24 of the sink C and is controlled by the valve 25. The pipe 2| leading to the flushing ring 20 may also be connected by 4 the valve 26 to the hot water line of the water system of the sink cabinet A. The hot water valve 21 for the faucet 24 is located on the opposite side of the sink to the valve 25.

I provide an air inlet passageway 28 which is adapted to receive air from the blower 29 which is operated by the motor 33 located in the base of the sink cabinet A. By this means, air may be blown into the bottom or bowl l6 of the incinerator compartment B to provide a forced draft when it is desired. I also provide a smoke or gas outlet 31 in the top of the incinerator compartment B which leads to the outside of the building and which permits gas and smoke to pass to the outside when the incinerator compartment B is in operation to consume any refuse which has been placed in the same.

An important feature of my invention resides in the combination of the kitchen cabinet incinerator A where the incinerator compartment B is located convenient to the sink C thus the housewife may readily discharge any garbage or refuse which is to be burned into the basket i l by opening the door l2. The convenient location of the compartment B to the sink C will be readily apparent owing to the fact that it saves time and steps for the housewife in disposing garbage and other refuse which ordinarily is burned and disposed of in an incinerator remotely located.

The burner is may be operated when it is desired to ignite the material in the basket [4 and when the burner i8 is in operation it is desirable that the door 12 be locked closed. Therefore, I provide a thermostatic control lock D. The lock D is illustrated in Figure 6 in sectional detail. The lock D may be of any form. A look bolt 33 is operated by a thermostatic coil 34 to drive the free end of the bolt 33 into the recess 35 in the wall of the compartment B so that when the incinerator compartment B is in operation the heat in the compartment will automatically lock the door 12 closed. The bolt 33 passes through the opening 36 in the side of the hinged door (2 asillustrated in Figures 1 and 6.

When the incinerator compartment unit has been operated to consume all of the refuse in the basket Hi, the ashes will fall through the grate bottom [5 and into the bowl IS. The door 12 can be slightly rocked to jar the ashes out of the basket into the bowl I6 if it is desired and the bowl It may be washed clean of the ashes by turning on one of the valves 23 or 26 and flushing hot or cold water into the bowl, washing the ashes down into the sewer through the passageway In this manner I provide a kitchen cabinet incinerator conveniently located for use of the housewife. It is also a feature to provide an incinerator built into the cabinet of the sink and which is heavily insulated so that the heat of the incinerator, when it is operating to consume the refuse therein, will not escape into the room where the cabinet C is located. The blower 29 will also carry any fumes or gases in the incinerator compartment B out through the flue 3| from the air circulating system provided in my incinerator and may also be used to dry out any moisture in the garbage or refuse waste in the basket it. The basket M is removable sothat it may be replaced or entirely removed anytime by opening the door i2 and lifting the basket M off its supporting connection on the inner face of the door 92. The air circulating means will alsodry out the bowl it of the incinerator whenever it is desired by operating the motor 30.

Figure "4 illustrates the section through the bottom of Figure 3 to indicate the basket l4 within the compartment B, also showing the heavy insulation II with an inner liner insulating It which insuresthe heat sealing of the incinerator compartment B.

Figure 5 is a section on the line 5+5 of Figure 3 lower than the section fi-4 and illustrates the burner 18 which also shows the air circulating fan .29 which is operated by the motor '30. These parts are all conveniently located and concealed within the cabinet A thus providing a streamlined attractive cabinet A wherein the incinerator is concealed as well as the connect-.- ing .parts' and valves such as 23 and .26.

'In Figure 7 I provide an alternate method of access to the basket 3! inside the compartment E by using a door which pulls outward like a drawer drawing the'basket 3! with it.

Fig-ure "7 shows the drawer 38 and the basket 31 'insection. As the drawer 38 is pulled out-- ward, a hinged bottom damper 39 lifts upward closing the bottom of the drawer as a result of pulling outward on the handle 45 of the drawer 38. The hinged bottom is hinged just belowthe bottom of the basket and adjacent to the inner face of the compartment drawer. As the draw r is pulled outward the shoulder 49 upon which the bottom of the door front rests automatically forces the hinged bottom 39 above mentioned upward closing off the bottom of the drawer. As the drawer is pulled from the compartment to the limits of its travel, the basket 3'5 may be removed. Near the top of the back wall of the inside of the compartment is an outlet ll for allowing smoke or gas to be passed to the outside of the buiding.

Directly below the basket in the compartment, resting on the compartment floor is an electric heater 42 for heating the incinerator compartment E to consume any refuse in the basket. Entering the side of the compartment E below the "heater 42 is an air inlet 43 leading from the blower 29 which provides a forced draft when motor 30 is in operation. Directly below the entrance of the air inlet into the compartment is located a water flushing ring ti which is adapted to flush the ashes into the outlet 45 leading to the sewer system of the building.

The compartment E is insulated by the heavy insulation l l and the inner insulation or ceramic wall II. The insulation II is also formed in the front of the door 38 so that the compartment E is completely insulated to prevent the heat from the incinerator escaping into the room where thesame is located. The compartment E is located within the cabinet A in the same manner as the incinerator compartment B is located therein. This places the compartment-E wholly within the cabinet A in a convenient location adjacent the sink 0.

The electric heater 42 can be of an suitable form. Asuitableelectric switch for turning the current on to .the heater 42 may be located on the front of the cabinet A in the same position as the timer I9 is located and the switch may include a timer for turning the heat oiT the heater 42 after a predetermined time, however, I have not shown the switch for the heater 42 in thedrawings.

The bottom of the basket 31 is perforated'or formed with a grate so that the ashes in the basket may sift through to the outlet 45. The

6 drawer can be slightly. vibrated to shake. the ashes into the outlet passage asit is desired. The damper-like bottom 39 closes automatically as the drawer 38 .is pulled out and thus any ashesremaining in the basket 31 will .be can fined. in the bottom of the drawer, however. when the drawer is pushed .into operative posi tion the hinged bottom '39 will fall down into the outlet. passageway .45 and will assist in jars ring the ashes :freefrom the basket 37 causing them to fall into the outlet passagewaylw.

In Figure 9 I have illustrated another form of my incinerator suchv as F which isalso adapts ed to be located inthe same position inthecabe inet A as the incinerator compartment B is 10-. cated, thus positioning the incinerator-:Fclose to the sink C and conveniently located in re! lation thereto.

The incinerator F .is insulated with the heavy insulating material H and the liner insulation which forms the walls of the incinerator Fahd which is similar to the fireproof material ll" heretofore described.

The incinerator F shownin Figure 9 employs a triangularshaped basket 48 which is secured to the swinging .door Y49 and which is formed with agrate-like bottom 50 through which the ashes from the basket may fall into the outlet opening 45. The door is hinged alongi-ts vertical edge 5| and thus the door is adapted to swing outwardly with its free edge as illustrated in dotted outline in Figure 9.

It will be apparent that I have illustrated different types of incinerator compartments such as B, E and F. The first type B'having a swings, ing door l2 which is hinged along its bottom edge. which can be pulled out to fully expose the basket 31 and the third type resides in a swinging door 49 which carries the triangular like basket 48 on its inner face and when the door is opened the basket is fully exposed and may be removed. In all three types of my incinerators the baskets I 3, 31 and respectively are removable. It is'also a feature of my incinera' tor to provide virtually an air tight compartment excepting for the inlet air passageway for a forced draft and an outlet passageway for the smoke and gases to escape to the atmosphere outside the building in is located. The flushing means is of-importance because it keeps the incinerator clean and thereby provides a sanitary means of disposing which the incinerator garbage and refuse which can be burned with I out dust or ashes from the same entering the kitchen or room in which the incinerator is located.

A feature of my invention resides in providing a unitary sink incinerator cabinet which maybe moved as a unit to any position where it is desired to be operated in a building. This unitary sink incinerator cabinet is connected as a whole to place the incinerator in the cabinet wh-iehree' ceives the sinkand is positioned directlyadjacent to the sink so that the garbage from the sink may be passed directly into the incinerator and wherein the water connections for flushing the sink will also be a part of the flushing system for flushing the ashes from the incinerator into the sewer. Therefore the sink cabinet and-incinerator unit are inseparable with cooperating parts which function together to provide a com plete unit cabinet which may be moved from place-to place or positioned wherever it is desired inc/building where-there is a supply of water and The second type E provides a drawer 38 a Sewer connection together with a source of fuel to supply heat to the incinerator and a smoke outlet.

The unitary incinerator cabinet may include a cabinet wherein a water, fuel and source of air is provided and wherein the incinerator compartment formed in the cabinet is completely insulated with a heavy wall of insulation completely surrounding the fire chamber of the incinerator. In a cabinet of this kind, the same may be portable so that it may be connected with a sewage system and the water supply system of any building. The unit may even include an oil burner having a fuel supply stored in the cabinet and adapted to supply the burner with fuel to heat the incinerator compartment and reduce the garbage or waste placed therein to ashes.

Figure 10 is a front view of the incinerator cabinet showing the location of the controls for the flushing unit and burner positioned inside the incinerator compartment and the control for the air ventilating supply.

In the drawing in Figure 10, I have illustrated an incinerator cabinet with the controls conveniently located on the cabinet so that the housewife may readily operate anyone of the controls from the outside of the cabinet to turn on the burner, or to flush the ashes out of the incinerator and to turn on the air fan to cause air to be circulated through the incinerator compartment. These controls are respectively the air control 52, the water supply control for the flushing unit 53, and the burner control 3, anyone of which may be operated separately anytime from a position outside the incinerator cabinet thereby making it convenient for the housewife to regulate the operation of my incinerator cabinet or these controls may be located inside the kitchen cabinet adjacent to the incinerator.

Heretofore incinerators were placed in remote positions of the building and were inconveniently located. My incinerator kitchen cabinet is streamlined and attractively built so that it is formed as an integral part with the cabinet A in which the sink C is located. This added convenience for the housewife will be readily apparent. To accomplish these results it is essential that the incinerator compartment be located in close proximity to the sink and water connections thereof and thus the incinerator forms a part of the kitchen sink cabinet. My incinerator could not be successfully operated without being a part of the water system of the sink. With the modern kitchens that are being installed at the present time, my kitchen cabinet incinerator and sink add a convenience heretofore unavailable.

The blower for the air to the incinerator may be controlled by a stack control (not illustrated in the drawings) which operates to start and stop the blower by the temperature in the stack. Thus the blower can be set to operate with the stack control so that when the temperature rises in the stack (smoke outlet) the blower will start to operate and when the temperature in the stack lowers the blower may be shut oif.

The incinerator unit is adapted to operate any place in the building where a supply of water is located together with a drain for the ashes and where heat may be obtained for burning the material in the incinerator. While it is preferred to have the incinerator as a part of the kitchen cabinet sink, it is obvious that the sink can be omitted but it is necessary to have a supply of water togetherwith a switch drain and a smoke outlet together with a fuel supply for the burner of the incinerator. It will be apparent that where fire brick insulating means is desired that the same may be replaced or built with fire proof ceramic material instead of fire brick so that a smooth uninterrupted wall of fire proof ceramic basket, a refuse outlet located in the bottom of said chamber and a water supply means so located with respect to said basket and said refuse outlet that means is provided for flushing ashes of incinerated material from said chamber through said refuse outlet.

2. A cabinet incinerator comprising, an insulated incinerator chamber, an insulated door on said chamber, said door hinged on the lower horizontal edge, a basket having openings in the lower portion thereof providing means for containing refuse removably attached to the inside of said door, said door being adapted to swing outward at the top and downward from said cabinet and means for incinerating refuse contained in said basket.
